Description
This application claims in the preferential of on 2 21st, 2018 10-2018-0020720 South Korea patent applications submitted
Power, the full content of the South Korea patent application are included herein by reference.
Technical field
This disclosure relates to a kind of display device, more particularly, to a kind of organic light-emitting diodes with reduced frame
Manage (OLED) display device.
Background technique
Organic Light Emitting Diode (OLED) display represents important display technology.With most of display devices now
Equally, OLED display generally includes display panel and touch panel.Display panel includes being configured to show the multiple of image
Pixel.Each of multiple pixels include Organic Light Emitting Diode (OLED) and the electricity for being configured to control Organic Light Emitting Diode
Road unit.Circuit unit includes at least control transistor, driving transistor and storage.Touch panel can be set aobvious
Show on panel to sense touch input and thus calculate touch coordinate.
Display circuit board is typically connected to display panel, and touch circuit plate is typically connected to touch panel.
Many display panels (such as OLED display) now are configured to be bent.However it is possible that being bent
It will appear crack when these display panels.These cracks, which will lead to display device, can not operate or cause other defect.
Summary of the invention
Display device includes the touch screen panel for defining effective coverage and non-active area thereon.Non-active area is at least
Part surrounds effective coverage.Touch screen panel include first while and when second.Display flexible printed circuit board is connected to touch screen
Panel.Show that the first side of flexible printed circuit board and touch screen panel is at least partly stacked.Flexible printed circuit board is touched to connect
It is connected to touch screen panel.The second side for touching flexible printed circuit board and touch screen panel is at least partly stacked.Touch flexible print
Printed circuit board is bent towards the lower surface of touch screen panel.Enhance component and touches lower surface and the touch of flexible printed circuit board
A part contact of the side surface of panel plate.Enhancing component is connected to the second side of touch screen panel.
Display device includes the display panel with the first side mainly extended in a first direction.Display panel has limit
It is scheduled on effective coverage thereon and non-active area.Non-active area is at least partially surrounding effective coverage.Display panel relative to
First extended in a first direction is referring to bending shaft.Touch-sensing unit is arranged on a display panel, and has with the
The second side that the second party that one direction intersects upwardly extends.Display flexible printed circuit board is connected to display panel.Display is flexible
First side of printed circuit board and display panel is at least partly stacked.It touches flexible printed circuit board and is connected to touch-sensing list
Member.The second side for touching flexible printed circuit board and touch-sensing unit is at least partly stacked.Touch flexible printed circuit board phase
For the second reference bending shaft extended in a second direction.Enhance a part and touch of the side surface of component and display panel
The contact of both lower surfaces of flexible printed circuit board.
